In grade school geography, way back in the early 50’s, we learned that Venezooweela was the only foreign place we got oil from to fight WW II. Lake Maracaibo had so much oil our guys didn’t actually have to drill very far for it. They mostly just kept scraping in off the lake and around the edges. The first problem was making a clean space to load the oil so that the tankers came out with clean hulls so as to avoid getting our own ports all oiled up. I’d be a bit surprised if anyone has actually drilled test holes deep enough to know just how much rotten Amazon foliage is actually buried there. And note that neighbor Columbia didn’t make the list but they have to be sitting on a grease pit also.
